52Fe骨髓显像与何种细胞的功能有关

A.网状巨噬细胞

B.粒细胞生成细胞

C.红细胞生成细胞

D.血小板生成细胞

E.淋巴细胞生成细胞

答案

参考答案：C

解析：1.52Fe进入血液后与血清转贴蛋白结合并参与合成血红蛋白，因此其骨髓显像功能与骨髓内的红细胞生成细胞有关。 2.静脉注射放射性胶体颗粒后，主要被体内网状内皮系统的巨噬细胞吞噬，因此Tc-硫胶体骨髓显像与骨髓网状巨噬细胞的功能有关 3.细胞非特异性交叉反应抗原95主要在胞浆、血液中粒细胞膜和骨髓中粒细胞生成细胞表达，且骨髓中粒细胞与外周血粒细胞之比高达50～100：1，因此99mTc-NCAA在体内主要分布于骨髓中。

单项选择题

The first and most important agents of socialization are the people who care for infants. In the earliest months, messages from nurturers constitute the child’s basic understanding of the world around it. This is the infant’s first introduction to the language that shapes perception and elicits emotion.
Another powerful source of information and socialization is the friendship of peers. Peers are equals that one can deal with on the same level as oneself, whereas parents are superiors. The heavy emotional overlay of family relationships makes some kinds of learning difficult.
Much formal socialization is placed in the hands of professionals. Teachers from kindergarten on are specifically designated agents of socialization. Ideally, a teacher is one who has both knowledge and the skills to present it. During the course of teaching their subjects, classroom instructors provide role models and attempt to convey the excitement of learning itself.
In earlier times, parents, friends and teachers would comprise the list of primary childhood socializers. Children’s books, comics and magazines might also have been mentioned as sources of information on norms and role models. Today one must add three powerful indirect or non-personal socialization agents: radio, movies and television. Many people learn about politics, form a vision of well-being, and develop attitudes towards others from what they see on the screen and hear through the speakers.

Peers are one of the ______ agents of socialization.

A．formal

B．indirect

C．primary

D．personal
